使用layui实现树形结构的方法

树形结构在项目中使用是比较，下面我来介绍一种layui做树形结构的方法

树形结构需要获得的数据有父id，所以数据库需要有父id：

后台代码：

@RequestMapping(value = "/lists") public void getList( HttpServletResponse response) { List list = this.companyService.getList(); String[] exclude={"Groups"}; JsonUtils.printJsonStringFromArrayObjectWithExclude(response, list, exclude); } public List getList(){ ChangeDataSource.changeDataSource(DataSource.dataSource2); String hql=" from Company"; return this.baseDao.exeQueryHql(hql); }

html中，需要引入js包

<div> <table> <div></div> <tbody> </tbody> </table> </div> <script src="https://www.jb51.net/layui/layui.js"></script> <script src="https://www.jb51.net/js/jquery-1.7.2.js"></script> <script src="https://www.jb51.net/js/jquery-ui.js"></script> <script src="https://www.jb51.net/js/jquery.treetable.js"></script> <script src="https://www.jb51.net/js/jquery.treetablebox.js"></script>

js中直接按照格式修改数据就可以了

layui.use([ 'layer', 'element'], function() { var layer = layui.layer; var tNodes = []; init(); function init() { var heads = ["公司名称", "部门名称", "公司地址", "联系人", "联系电话"]; $.ajax({ type: "post", url: basePath + "/company/lists", data:{"token":token}, async: true, success: function(data) { if("暂无数据" == data) { layer.msg('暂无数据请添加数据', { icon: 2, time: 1000 }); } else { data = eval("(" + data + ")"); var tNodes = '['; for(var obj in data) { var companyName = data[obj].companyName; var departmentName = data[obj].departmentName; var address = data[obj].address; var linkman; var contactNumber = data[obj].contactNumber; if(data[obj].linkman.length > 10) { linkman = data[obj].linkman.substring(0, 10) + "..."; } else { linkman = data[obj].linkman; if(linkman == "" || linkman == null || linkman == "undefined") { linkman = "暂无"; } } if(departmentName == "" || departmentName == null || departmentName == "undefined") { departmentName = "暂无"; } else { departmentName = data[obj].departmentName; } if(data[obj].companyId == "" || data[obj].companyId == null) { tNodes += '{ id: ' + data[obj].companyId + ', pId: ' + data[obj].company + ', name: "' + companyName + '", td: ["' + departmentName + '","' + address + '","' + linkman + '","' + contactNumber + '"] },' } else { tNodes += '{ id: ' + data[obj].companyId + ', pId: ' + data[obj].company + ', name: "' + companyName + '", td: ["' + departmentName + '","' + address + '","' + linkman + '","' + contactNumber + '"] },' } } tNodes += ']'; tNodes = tNodes.replace(",]", "]"); tNodes = tNodes.replace(/\s+/g, ""); tNodes = tNodes.replace(/<\/?.+?>/g, ""); tNodes = tNodes.replace(/[\r\n]/g, ""); $.TreeTable("treeMenu", heads, eval("(" + tNodes + ")")); $('#treeMenu').treetable('expandAll'); layui.use('form', function() { var form = layui.form; form.render(); form.render('select'); }); } }, error: function(XMLHttpRequest, textStatus, errorThrown) { layer.msg('抱歉，服务器刚刚打了个盹！', { icon: 2, time: 2000 }); } }); } });
